Answer:
-2x-1
Solution:
(8x-4)-(10x-3)
= 8x - 4 -10x +3.
Remove the parenthesis. This includes multiplying the the negative outside the parenthesis to its next term. (-) (10x) = -10x and (-)(-3) = +3
= 8x - 4 - 10x + 3
Collect like terms , 8x + (-10x) = -2x and -4 + 3 = -1
= -2x -1
since that form can't be simplified , we'll stop here. That's the answer
